Title: Method of layout design
Inventor: MUROFUSHI MASAKO
IPC: H01L21/82
Filed: 1992-06-05
Abstract: PURPOSE:To set a path delay restriction wherein a path critical in terms of timing is extracted easily by providing a means wherein a minimum slack value in subpaths which posses a branch and junction jointly is set as a delay restriction with reference to each subpath. CONSTITUTION:Information on a net stroke and timing request is input; a path is extracted. A request for the delay time with reference to a net component for the path which has been extracted is allocated to each net and the request time is set for each set. A virtual wiring length is estimated for each net; the delay time which is estimated is found; a net slack value as the difference between the request time and the estimated delay time is computed. The path is disintegrated into subpaths a branch and junction; a subpath slack is found, for each subpath, from the sum of values of slacks in a net constituting the subpaths. The difference in the subpath slack between the subpaths which process the branch and meeting point jointly is found as a DELTA subpath slack; it is set as a restriction with reference to the related subpaths.

Abstract: PURPOSE:To enlarge the mechanical strength of a plastic product and reduce its expansion and contraction and, at the same time, make its flexibility favorable by a method wherein molding is performed by pouring molten plastic in a mold under the condition that a wire gauze is held in the mold. CONSTITUTION:Molding is performing by pouring molten plastic in a mold under the condition that wire gauze 2 is cut with scissors or the like into th desired shape and held in the mold. In order to hold the wire gauze 2 in one plane, its holding is performed by magnetic force of magnets arranged in the mold in case of the magnetically attractable wire gauze or by the tension applied to the periphery of the wire gauze for preventing the wire gauze from bending in case of the non-magnetic wire gauze. In the plastic product 3 produced by imbedding the wire gauze 2 as described above its mechanical strength is larger due to the bonding between plastic layers 1 and the wire gauze 2 and its expansion and contraction is small due to the strong restriction in the stretching direction by the wire gauze 2. Further, the product has large flexibility and is easily bent due to the imbedded wire gauze, which is flexible to two dimensional deformation.

Abstract: PURPOSE:To enhance the throughput of a printer as a whole, by a method wherein the acceleration and deceleration at the time of sheet feed is performed slowly at the time of friction feed but performed quickly at the time of pin feed by the control operation of a sheet feed motor. CONSTITUTION:In a control apparatus 30, when a friction feed mode is selected by a change-over switch 31, an acceleration/deceleration table T2 at a slow acceleration/deceleration time is read from ROM and the driving control signal according to the table T2 is sent out to a sheet feed motor 15 and slow acceleration/deceleration operation is performed under frequency control to make it possible not only to perform accurate sheet feed without generating slip but also to keep a feed speed sufficiently high. When a pin feed mode is selected, an acceleration/deceleration table T1 at a quick acceleration/ deceleration time is read from ROM and the feed motor 15 performs sharp acceleration/deceleration and generates a high sheet feed speed. By this method, sufficiently high speed sheet feed is obtained while the generation of the shift or jamming of a sheet is prevented and throughput is enhanced.

Title: Method for correcting proximity effect in electron beam lithography
Inventor: WAKIMOTO OSAMU
IPC: H01L21/027
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To perform smooth pattern stitching without dividing a pattern finely even if a correction value is greatly changed. SOLUTION: A proximity effect correction unit 24 obtains an inclination amount in X and Y directions of a corrected value from the proximity effect corrected amount of a square itself to be shot and an area therearound, and prepare a signal to control the changing amount of a square size on the basis of the inclination amount. The signal to control the size in X and Y directions is aupplied to a molding deflector control circuit 16. The circuit 16 sets the size in Y direction to a specified value in the first shot stage, and controls the size in X direction so that it may change continuously from zero. Then, in the later stage, the circuit 16 sets the size in X direction to a specified value, and controls the size in Y direction so that it may become smaller continuously.  Because of such a controlling operation, the proximity effect can be corrected in a high accuracy even if the correction amount is greatly changed.
